[0046] To facilitate understanding of the embodiments of the present application, the interactive extension technology related to the present application is described.

[0047] The Graphical Language Transmit Format (glTF) is an open standard for transmitting and loading 3D models. It aims to provide a lightweight, efficient, and scalable 3D model format for fast loading and rendering on platforms such as engines and mobile devices. The glTF format supports a variety of 3D model elements, including geometry, materials, textures, animations, and scenes. Due to its openness and efficiency, the glTF format has been widely adopted in engines and mobile devices, becoming a key standard for transmitting and loading 3D models.

[0048] Figure 2 shows a schematic diagram of the structure of a glTF file. As can be seen, the glTF file includes multiple object nodes.

[0049] For example, the scene is the entry point of the glTF file. A gltf file may store multiple scenes, each of which contains one or more nodes. The node points to the mesh, camera, and skin, and is used to describe the various deformations of the node. Mesh: represents the geometric objects in the scene. Camera: used to define the view configuration of the rendered scene; skin is bound to the animation. Accessor is used as an abstract source of data and can be accessed by mesh, skin, and animation, and provides geometric data, skin parameters, and animation values ​​that change over time. Material is the appearance object when the geometric object is rendered, which is used to define the appearance parameters of the geometric object. Animation: used to define the changes of the node (such as rotation and translation); Texture: contains sampler and image, which together define how to map the texture to the model, among which images are used to locate the image resource; sampler: used to define the sampling and filtering method of the image. BufferView is used to get real data from the buffer.

[0050] In related technologies, the Moving Pictures Experts Group (MPEG) interactively extended glTF and designed relevant standards for interactivity.

[0051] Interactivity is defined based on behavior, which includes a trigger node and an action node. The trigger conditions for a trigger node include collision conditions, proximity conditions, and visibility conditions. Actions include tactile feedback actions (i.e., ACTION_SET_HAPTIC) and activation actions (ACTION_ACTIVATE).

[0052] However, there is no interaction standard related to tactile signals in the prior art. Therefore, how to describe tactile signals is an urgent problem to be solved.

[0053] The method for generating tactile signals provided by the embodiments of the present application will be described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0054] FIG3 is a schematic diagram of a method for generating a tactile signal according to an embodiment of the present application. As shown in FIG3 , the method 300 includes at least part of the following:

[0055] S310, obtaining signal attenuation information of a tactile signal;

[0056] S320: Generate the tactile signal according to the signal attenuation information of the tactile signal.

[0057] In some embodiments, signal attenuation information of a haptic signal is used to describe the interaction between a haptic source and an avatar (or an object executing the haptic signal). Therefore, a haptic signal can be generated based on the signal attenuation information of the haptic signal.

[0058] In some embodiments, the method may be executed by an electronic device, for example, by the terminal 110 in FIG. 1 , or by the server 120 in FIG. 1 , which is not limited in this application.

[0059] In some embodiments, the signal attenuation information of the haptic signal includes at least one of the following:

[0060] distance-related signal attenuation information;

[0061] Time-dependent signal attenuation information;

[0062] Signal attenuation information related to occluders;

[0063] Signal attenuation information related to body parts;

[0064] Information on pressure-related signal attenuation.

[0065] That is, in the embodiment of the present application, when constructing the tactile signal model, the signal attenuation related to at least one factor among distance, time, obstructions, body parts and pressure is taken into account, which is conducive to ensuring that the tactile signal model provided by the embodiment of the present application can more accurately simulate the presentation form of the tactile signal in the real environment, thereby improving the accuracy of the tactile signal model.

[0066] It should be understood that the present application does not limit the type of tactile signal. For example, the tactile signal may be triggered by vibration, heat, wind, rain, etc.

[0067] In some embodiments, the signal attenuation information of the tactile signal is carried in a first object. For example, the first object includes at least one of the following:

[0068] The tactile source object corresponding to the tactile signal, the avatar object corresponding to the tactile signal, the trigger node object corresponding to the tactile signal, the action node object (or trigger action object, i.e., HapticActionNode object) corresponding to the tactile signal, and the occlusion object corresponding to the tactile signal.

[0069] In some embodiments, signal attenuation information of the haptic signal may be carried in the attribute information of the first object.

[0070] It should be understood that the signal attenuation information of the haptic signal can be carried in the same object, or in multiple objects, and this application is not limited to this. For example, part of the signal attenuation information of the haptic signal can be carried in the haptic source object, and the remaining information can be carried in the action node object.

[0071] In some embodiments, the first object may be a glTF object.

[0072] In some embodiments, when the signal attenuation information of the tactile signal is carried in a trigger action node object, the signal attenuation information of the tactile signal can be carried in a child node of the trigger action node object, for example, carried in a trigger action media object (HapticActionMedia object), wherein the trigger action media object points to a tactile data file object, for example, the trigger action media object includes address information of the tactile data file.

[0073] In some embodiments of the present application, the S310 includes:

[0074] Get the first object;

[0075] The first object is analyzed to obtain signal attenuation information of the tactile signal.

[0076] In some embodiments, the first object can be obtained locally by the tactile signal generating device, or it can be obtained from other devices, such as from a server, which can be, for example, an object storage service platform, or a network attached storage (NAS).

[0077] In some embodiments of the present application, the S320 includes:

[0078] The haptic signal is rendered according to the signal attenuation information of the haptic signal.

[0079] In some embodiments, the haptic signal generating device may include a rendering engine (presentation engine), which may render the haptic signal according to signal attenuation information of the haptic signal.

[0080] In some embodiments, the first object is associated with one or more scenes. Rendering the haptic signal may include rendering the haptic signal in the scene associated with the first object.

[0081] For example, in the scene where the first object is located, the tactile source and the tactile signal execution object (i.e., the avatar) are rendered, the distance between the tactile source and the tactile signal execution object is determined, and whether there is an obstruction between the tactile source and the tactile signal execution object is determined, and then the tactile signal is rendered based on the signal attenuation information related to the distance and the signal attenuation information related to the obstruction.

[0082] For another example, in the scene where the first object is located, the haptic source and the haptic signal execution object (ie, the avatar) are rendered, and the haptic signal is rendered according to the triggering time of the haptic signal and the time-related signal attenuation information.

[0083] For another example, in the scene where the first object is located, the tactile source and the tactile signal execution object (ie, avatar) are rendered, and tactile signals of different body parts of the tactile signal execution object are rendered according to signal attenuation information related to the body parts.

[0084] For another example, in the scene where the first object is located, the tactile source and the tactile signal execution object (i.e., the avatar) are rendered, and the tactile signal felt by the tactile signal execution object is rendered based on the force with which the tactile signal execution object contacts or presses the tactile source and combined with the signal attenuation information related to pressure.

[0085] The following describes the specific implementations of the above-mentioned signal attenuation information in conjunction with specific embodiments.

[0086] Example 1: Distance-related signal attenuation information

[0087] In some embodiments, the distance-related signal attenuation information can be used to characterize the signal attenuation caused by distance factors. For example, the shock or heat energy caused by an explosion will attenuate as the distance from the explosion center increases.

[0088] In some embodiments, the distance-related signal attenuation information includes but is not limited to at least one of the following:

[0089] a signal attenuation parameter, used to determine an attenuation amount of the tactile signal;

[0090] an indication of a signal attenuation manner of the tactile signal;

[0091] an enable or disable indication, used to indicate whether to enable the distance-related signal attenuation information when generating the tactile signal;

[0092] The tactile signal type indication is used to indicate the type of the tactile signal to which the distance-related signal attenuation information is applicable.

[0093] Exemplarily, each information in the distance-related signal attenuation information may be carried in at least one of the following objects:

[0094] The tactile source object corresponding to the tactile signal, the avatar object corresponding to the tactile signal, the trigger node object corresponding to the tactile signal, and the action node object corresponding to the tactile signal (for example, carried in a child node of the action node object, such as a trigger action media object).

[0095] In some embodiments, the signal attenuation manner of the haptic signal is indicated to indicate at least one of the following manners:

[0096] Attenuation is performed by a fixed attenuation amount, attenuation is performed based on a preset signal attenuation method (for example, based on a preset signal attenuation formula), or attenuation is performed based on a user-defined signal attenuation method (for example, based on a user-defined signal attenuation formula).

[0097] In some embodiments, when there are multiple preset signal attenuation methods, the signal attenuation method indication of the tactile signal can also indicate a target preset signal attenuation method among the multiple preset signal attenuation methods, for example, indicating a target signal attenuation formula among multiple preset signal attenuation formulas.

[0098] In some embodiments, the plurality of preset signal attenuation modes include but are not limited to at least one of the following:

[0099] Inverse distance decay method, linear distance decay method, exponential distance decay method, inverse square decay method.

[0100] In some embodiments, for the inverse distance attenuation method, the following formula (also called the inverse distance attenuation formula) can be used to determine the feedback intensity ida(d,md,rf) of the tactile signal:

[0101] Where md is the maximum distance, rf is the roll factor, rd is the reference distance, and d is the distance for calculating range gain.

[0102] In some embodiments, for the linear distance attenuation method, the following formula (also called the linear distance attenuation formula) can be used to determine the feedback intensity lda(d,md,rf) of the tactile signal:

[0103] Where md is the maximum distance, rf is the roll factor, rd is the reference distance, and d is the distance for calculating range gain.

[0104] In some embodiments, for the exponential distance decay method, the following formula (also called the exponential distance decay formula) can be used to determine the feedback intensity eda(d,md,rf) of the tactile signal:

[0105] Where md is the maximum distance, rf is the roll factor, rd is the reference distance, and d is the distance for calculating range gain.

[0106] In some embodiments, the signal attenuation parameter may include one of the following parameters:

[0107] Attenuation coefficient α, initial tactile feedback strength F obtained from the tactile source max ;

[0108] The attenuation coefficient is inversely proportional to the square of the distance. For example, when the distance R from the tactile source is within the target range (e.g., D min <R≤D max ), the attenuation coefficient is inversely proportional to the square of the distance.

[0109] In some embodiments, the S320 may include:

[0110] determining a feedback intensity of the tactile signal according to the signal attenuation parameter;

[0111] The haptic signal is generated according to the feedback strength of the haptic signal.

[0112] For example, the feedback intensity F of the tactile signal is determined according to the following formula: F=αF max

[0113] Where α is the attenuation coefficient, F max Indicates the initial feedback strength obtained from the tactile source;

[0114] Among them, the change function of α can be expressed as:

[0115] Among them, α min is the minimum value of the attenuation coefficient, D min and D min is a predefined value.

[0116] That is, within a certain distance range, for example, less than D min Within the range, it can be considered that the feedback intensity of the tactile signal does not decay, that is, the attenuation coefficient α is set to 1. After exceeding a certain distance range, for example, greater than Dmax , the attenuation coefficient α is set to 0.

[0117] In some embodiments,

[0118] The relationship between the feedback strength of the tactile signal and the distance obtained by this function is shown in FIG4 , wherein the feedback strength of the tactile signal is a monotonically decreasing interval between the minimum and maximum distance values.

[0119] In some embodiments, the customized signal attenuation method may be a signal attenuation method customized by the device manufacturer, that is, not a signal attenuation method specified by the standard.

[0120] In some embodiments, the signal attenuation parameter includes a fixed attenuation amount.

[0121] For example, when using a fixed attenuation, a target attenuation for signal attenuation may be further indicated. For example, the fixed attenuation may be infinite, 0, or any other value. Alternatively, the target attenuation for signal attenuation may not be indicated. In this case, signal attenuation is performed based on a default attenuation, which may be predefined or user-set.

[0122] In some embodiments, when a preset signal attenuation method is adopted for attenuation, the signal attenuation parameter includes a parameter used to calculate the attenuation amount of the tactile signal based on a target preset signal attenuation method.

[0123] For example, when attenuation is performed based on a preset signal attenuation method, the signal attenuation parameter may be carried in a first object, such as a tactile source object or an action node object.

[0124] In some embodiments, when the inverse distance decay method, the linear distance decay method, or the exponential distance decay method is used, the signal attenuation parameter may include at least one of the following parameters:

[0125] md represents the maximum distance, rf represents the roll factor, rd represents the reference distance, and d represents the distance for calculating the range gain.

[0126] In some embodiments, when the inverse square attenuation method is adopted, the signal attenuation parameter may include at least one of the following parameters:

[0127] α, represents the attenuation coefficient that changes with distance R, D min 、D max .

[0128] Optionally, when there are multiple preset signal attenuation modes, the signal attenuation mode indication is used to indicate the target signal attenuation mode among the multiple preset signal attenuation modes and the signal attenuation parameters involved in the target signal attenuation mode. The signal attenuation mode indication and the signal attenuation parameters can both be carried in a first object, such as a tactile source object or an action node object.

[0129] In some embodiments, when based on a customized signal attenuation method, the signal attenuation information of the haptic signal may include a customized signal attenuation parameter.

[0130] In some embodiments, the enable or disable indication is used to indicate whether to enable the distance-related signal attenuation information (or, whether to enable the signal attenuation parameter and / or signal attenuation mode indication) when generating the tactile signal, or to determine whether to consider the signal attenuation caused by the distance factor when generating the tactile signal.

[0131] In some embodiments, when the enable or disable indication is used to indicate enabling of the distance-related signal attenuation information, the distance-related signal attenuation information is considered when generating the haptic signal. When the distance-related signal attenuation information is disabled, the distance-related signal attenuation information is not considered when generating the haptic signal.

[0132] In some embodiments, the tactile signal type indication is used to indicate the type of tactile signal to which the distance-related signal attenuation information applies.

[0133] In some embodiments, signal attenuation due to distance factors may only be effective for specific types of tactile signals (e.g., vibration, thermal energy), or in other words, only for specific types of trigger sources, such as vibration, thermal energy, etc. Therefore, when describing the signal attenuation information due to distance factors, the applicable tactile signal type can be added. In this way, for tactile signals of this tactile signal type, the signal attenuation information can be used to generate a tactile signal, which helps ensure the accuracy of the tactile signal model.

[0134] Example 2: Time-dependent signal attenuation information

[0135] In some embodiments, the time-related signal attenuation information can be used to characterize the signal attenuation caused by time factors. For example, the shock or temperature caused by an explosion will decay over time.

[0136] In some embodiments, the time-dependent signal attenuation information includes at least one of the following:

[0137] a signal attenuation parameter, used to determine an attenuation amount of the tactile signal;

[0138] an indication of a signal attenuation manner of the tactile signal;

[0139] an enable or disable indication, used to indicate whether to enable the time-related signal attenuation information when generating the tactile signal;

[0140] The tactile signal type indication is used to indicate the type of the tactile signal to which the time-related signal attenuation information is applicable.

[0141] Exemplarily, each information in the time-related signal attenuation information may be carried in at least one of the following objects:

[0142] The tactile source object corresponding to the tactile signal, the avatar object corresponding to the tactile signal, the trigger node object corresponding to the tactile signal, and the action node object corresponding to the tactile signal (for example, carried in a child node of the action node object, such as a trigger action media object).

[0143] In some embodiments, the signal attenuation manner of the haptic signal is indicated to indicate at least one of the following manners:

[0144] Attenuation is performed by a fixed attenuation amount, attenuation is performed based on a preset signal attenuation method (for example, based on a preset signal attenuation formula), or attenuation is performed based on a user-defined signal attenuation method (for example, based on a user-defined signal attenuation formula).

[0145] In some embodiments, when there are multiple preset signal attenuation methods, the signal attenuation method indication of the tactile signal can also indicate a target preset signal attenuation method among the multiple preset signal attenuation methods, for example, indicating a target signal attenuation formula among multiple preset signal attenuation formulas.

[0146] In some embodiments, the customized signal attenuation method may be a signal attenuation method customized by the device manufacturer, that is, not a signal attenuation method specified by the standard.

[0147] In some embodiments, the signal attenuation parameter includes a fixed attenuation amount.

[0148] For example, when using a fixed attenuation, a target attenuation for signal attenuation may be further indicated. For example, the fixed attenuation may be infinite, 0, or any other value. Alternatively, the target attenuation for signal attenuation may not be indicated. In this case, signal attenuation is performed based on a default attenuation, which may be predefined or user-set.

[0149] In some embodiments, when a preset signal attenuation method is adopted for attenuation, the signal attenuation parameter includes a parameter used to calculate the attenuation amount of the tactile signal based on a target preset signal attenuation method.

[0150] For example, when attenuation is performed based on a preset signal attenuation method, the signal attenuation parameter may be carried in a first object, such as a tactile source object or an action node object.

[0151] Optionally, when there are multiple preset signal attenuation modes, the signal attenuation mode indication is used to indicate the target signal attenuation mode among the multiple preset signal attenuation modes and the signal attenuation parameters involved in the target signal attenuation mode. The signal attenuation mode indication and the signal attenuation parameters can both be carried in a first object, such as a tactile source object or an action node object.

[0152] In some embodiments, when based on a customized signal attenuation method, the signal attenuation information of the haptic signal may include a customized signal attenuation parameter.

[0153] In some embodiments, the enable or disable indication is used to indicate whether to enable the time-related signal attenuation information (or, whether to enable the signal attenuation parameter and / or signal attenuation mode indication) when generating the tactile signal, or to determine whether to consider the signal attenuation caused by the time factor when generating the tactile signal.

[0154] In some embodiments, when the enable or disable indication indicates enabling of the time-dependent signal attenuation information, the time-dependent signal attenuation information is considered when generating the haptic signal. When the time-dependent signal attenuation information is disabled, the time-dependent signal attenuation information is not considered when generating the haptic signal.

[0155] In some embodiments, the haptic signal type indication is used to indicate the type of the haptic signal to which the time-related signal attenuation information applies.

[0156] In some embodiments, signal attenuation due to time factors may only be effective for specific types of haptic signals (e.g., vibration, thermal energy), or in other words, only for specific types of trigger sources, such as vibration, thermal energy, etc. Therefore, when describing the signal attenuation information due to time factors, the applicable haptic signal type can be added. In this way, for haptic signals of this haptic signal type, this signal attenuation information can be used to generate a haptic signal, which helps ensure the accuracy of the haptic signal model.

[0157] Example 3: Signal attenuation information related to obstructions

[0158] In some embodiments, the signal attenuation information related to the obstruction may be used to characterize the signal attenuation caused by the obstruction. For example, an obstruction such as a wall may block the vibration or heat energy caused by an explosion.

[0159] In some embodiments, the signal attenuation information related to the obstruction includes at least one of the following:

[0160] a signal attenuation parameter, used to determine an attenuation amount of the tactile signal;

[0161] an indication of a signal attenuation manner of the tactile signal;

[0162] an enable or disable indication, used to indicate whether to enable the signal attenuation information related to the obstruction when generating the tactile signal;

[0163] The tactile signal type indication is used to indicate the type of tactile signal to which the signal attenuation information related to the obstruction is applicable.

[0164] Exemplarily, each information in the signal attenuation information related to the obstruction may be carried in at least one of the following objects:

[0165] The tactile source object corresponding to the tactile signal, the avatar object corresponding to the tactile signal, the trigger node object corresponding to the tactile signal, the action node object corresponding to the tactile signal, and the occlusion object corresponding to the tactile signal (for example, carried in the child node of the action node object, such as the trigger action media object).

[0166] In some embodiments, the signal attenuation manner of the haptic signal is indicated to indicate at least one of the following manners:

[0167] Attenuation is performed by a fixed attenuation amount, attenuation is performed based on a preset signal attenuation method (for example, based on a preset signal attenuation formula), or attenuation is performed based on a user-defined signal attenuation method (for example, based on a user-defined signal attenuation formula).

[0168] In some embodiments, when there are multiple preset signal attenuation methods, the signal attenuation method indication of the tactile signal can also indicate a target preset signal attenuation method among the multiple preset signal attenuation methods, for example, indicating a target signal attenuation formula among multiple preset signal attenuation formulas.

[0169] In some embodiments, the customized signal attenuation method may be a signal attenuation method customized by the device manufacturer, that is, not a signal attenuation method specified by the standard.

[0170] In some embodiments, the signal attenuation parameter includes a fixed attenuation amount.

[0171] For example, when using a fixed attenuation, a target attenuation for signal attenuation may be further indicated. For example, the fixed attenuation may be infinite, 0, or any other value. Alternatively, the target attenuation for signal attenuation may not be indicated. In this case, signal attenuation is performed based on a default attenuation, which may be predefined or user-set.

[0172] In some embodiments, when a preset signal attenuation method is adopted for attenuation, the signal attenuation parameter includes a parameter used to calculate the attenuation amount of the tactile signal based on a target preset signal attenuation method.

[0173] For example, when attenuation is performed based on a preset signal attenuation method, the signal attenuation parameter may be carried in a first object, such as a tactile source object or an action node object.

[0174] Optionally, when there are multiple preset signal attenuation modes, the signal attenuation mode indication is used to indicate the target signal attenuation mode among the multiple preset signal attenuation modes and the signal attenuation parameters involved in the target signal attenuation mode. The signal attenuation mode indication and the signal attenuation parameters can both be carried in a first object, such as a tactile source object or an action node object.

[0175] In some embodiments, when based on a customized signal attenuation method, the signal attenuation information of the haptic signal may include a customized signal attenuation parameter.

[0176] In some embodiments, the enable or disable indication is used to indicate whether to enable the signal attenuation information related to the obstruction (or, whether to enable the signal attenuation parameter and / or signal attenuation mode indication) when generating the tactile signal, or to determine whether to consider the signal attenuation caused by the obstruction when generating the tactile signal.

[0177] In some embodiments, when the enable or disable indication indicates enabling of signal attenuation information related to an obstruction, the signal attenuation information related to the obstruction is considered when generating a haptic signal. When the signal attenuation information related to the obstruction is disabled, the signal attenuation information related to the obstruction is not considered when generating a haptic signal.

[0178] In some embodiments, the tactile signal type indication is used to indicate the type of tactile signal to which the signal attenuation information related to the obstruction is applicable.

[0179] In some embodiments, signal attenuation due to obstructions may only be effective for specific types of tactile signals (e.g., vibration, thermal energy), or in other words, only for specific types of trigger sources, such as vibration, thermal energy, etc. Therefore, when describing the signal attenuation information due to obstructions, the applicable tactile signal type can be added. In this way, for tactile signals of this tactile signal type, this signal attenuation information can be used to generate a tactile signal, which helps ensure the accuracy of the tactile signal model.

[0180] In some embodiments, the attribute information of the first object includes an occluder indication, where the occluder indication is used to indicate whether the first object is an occluder. For example, if the first object is an occluder, the haptic signal is generated based on the signal attenuation information related to the occluder. If the first object is not an occluder, the signal attenuation information related to the occluder is not considered when generating the haptic signal.

[0181] Example 4: Signal attenuation information related to body parts

[0182] In some embodiments, the body part-related signal attenuation information can be used to characterize the signal attenuation caused by the tactile sensitivity of different body parts. For example, different body parts have different tactile sensitivities, such as fingertips being more sensitive and the back of the hand being less sensitive. Therefore, the tactile signals perceived by different body parts are also different.

[0183] In some embodiments, the signal attenuation information related to the body part includes at least one of the following:

[0187] a tactile signal type indication, used to indicate the type of tactile signal to which the signal attenuation information related to the body part is applicable;

[0188] A body part identifier is used to indicate the body part used for the signal attenuation parameter or the signal attenuation mode indication.

[0189] Exemplarily, each piece of information in the signal attenuation information related to a body part may be carried in at least one of the following objects:

[0190] The tactile source object corresponding to the tactile signal, the avatar object corresponding to the tactile signal, the trigger node object corresponding to the tactile signal, and the action node object corresponding to the tactile signal (for example, carried in a child node of the action node object, such as a trigger action media object).

[0191] In some embodiments, the signal attenuation manner of the haptic signal is indicated to indicate at least one of the following manners:

[0192] Attenuation is performed by a fixed attenuation amount, attenuation is performed based on a preset signal attenuation method (for example, based on a preset signal attenuation formula), or attenuation is performed based on a user-defined signal attenuation method (for example, based on a user-defined signal attenuation formula).

[0193] In some embodiments, when there are multiple preset signal attenuation methods, the signal attenuation method indication of the tactile signal can also indicate a target preset signal attenuation method among the multiple preset signal attenuation methods, for example, indicating a target signal attenuation formula among multiple preset signal attenuation formulas.

[0194] In some embodiments, the customized signal attenuation method may be a signal attenuation method customized by the device manufacturer, that is, not a signal attenuation method specified by the standard.

[0195] In some embodiments, the signal attenuation parameter includes a fixed attenuation amount.

[0196] For example, when using a fixed attenuation, a target attenuation for signal attenuation may be further indicated. For example, the fixed attenuation may be infinite, 0, or any other value. Alternatively, the target attenuation for signal attenuation may not be indicated. In this case, signal attenuation is performed based on a default attenuation, which may be predefined or user-set.

[0197] In some embodiments, when a preset signal attenuation method is adopted for attenuation, the signal attenuation parameter includes a parameter used to calculate the attenuation amount of the tactile signal based on a target preset signal attenuation method.

[0198] For example, when attenuation is performed based on a preset signal attenuation method, the signal attenuation parameter may be carried in a first object, such as a tactile source object or an action node object.

[0199] Optionally, when there are multiple preset signal attenuation modes, the signal attenuation mode indication is used to indicate the target signal attenuation mode among the multiple preset signal attenuation modes and the signal attenuation parameters involved in the target signal attenuation mode. The signal attenuation mode indication and the signal attenuation parameters can both be carried in a first object, such as a tactile source object or an action node object.

[0200] In some embodiments, when based on a customized signal attenuation method, the signal attenuation information of the haptic signal may include a customized signal attenuation parameter.

[0201] In some embodiments, the enable or disable indication is used to indicate whether to enable the signal attenuation information related to the body part (or, whether to enable the signal attenuation parameter and / or signal attenuation mode indication) when generating the tactile signal, or to determine whether to consider the signal attenuation caused by the body part when generating the tactile signal.

[0202] In some embodiments, when the enable or disable indication is used to indicate enabling of the signal attenuation information related to the body part, the signal attenuation information related to the body part is considered when generating the haptic signal. When the signal attenuation information related to the body part is disabled, the signal attenuation information related to the body part is not considered when generating the haptic signal.

[0203] In some embodiments, the tactile signal type indication is used to indicate the type of tactile signal to which the signal attenuation information related to the body part is applicable.

[0204] In some embodiments, signal attenuation due to body part factors may only be effective for specific types of tactile signals (e.g., thermal energy), or in other words, only for specific types of trigger sources, such as thermal energy. Therefore, when describing the signal attenuation information due to body part factors, the applicable tactile signal type can be added. In this way, for tactile signals of this tactile signal type, this signal attenuation information can be used to generate a tactile signal, which helps ensure the accuracy of the tactile signal model.

[0205] In some embodiments, the body part identifier is used to indicate the body part used for the signal attenuation parameter and / or the signal attenuation mode indication. Optionally, the body part-related signal attenuation information may include at least one body part-related signal attenuation information.

[0206] For example, the sensitivity value S of each body part of the tactile signal execution object is set, for example, the value range is [0.0, 1.0], which is used to describe the ratio of the feedback strength of the tactile signal felt by this body part, and the final perceived feedback strength F of the tactile signal p =S*F, where F is the original feedback strength value.

[0207] Example 5: Signal attenuation information related to pressure

[0208] In some embodiments, different contact or pressure granularity may result in different signal attenuation or enhancement. The pressure-related signal attenuation information can be used to characterize the signal attenuation or enhancement caused by different pressures. For example, the greater the pressure (the degree of deformation), the stronger the tactile signal.

[0209] In some embodiments, the pressure-related signal attenuation information includes at least one of the following:

[0210] a signal attenuation parameter, used to determine an attenuation amount of the tactile signal;

[0211] an indication of a signal attenuation manner of the tactile signal;

[0212] an enable or disable indication, used to indicate whether to enable the pressure-related signal attenuation information when generating the tactile signal;

[0213] The tactile signal type indication is used to indicate the type of the tactile signal to which the pressure-related signal attenuation information is applicable.

[0214] Exemplarily, each piece of information in the signal attenuation information related to a body part may be carried in at least one of the following objects:

[0215] The tactile source object corresponding to the tactile signal, the avatar object corresponding to the tactile signal, the trigger node object corresponding to the tactile signal, and the action node object corresponding to the tactile signal (for example, carried in a child node of the action node object, such as a trigger action media object).

[0216] In some embodiments, the signal attenuation manner of the haptic signal is indicated to indicate at least one of the following manners:

[0217] Attenuation is performed by a fixed attenuation amount, attenuation is performed based on a preset signal attenuation method (for example, based on a preset signal attenuation formula), or attenuation is performed based on a user-defined signal attenuation method (for example, based on a user-defined signal attenuation formula).

[0218] In some embodiments, when there are multiple preset signal attenuation methods, the signal attenuation method indication of the tactile signal can also indicate a target preset signal attenuation method among the multiple preset signal attenuation methods, for example, indicating a target signal attenuation formula among multiple preset signal attenuation formulas.

[0219] In some embodiments, the customized signal attenuation method may be a signal attenuation method customized by the device manufacturer, that is, not a signal attenuation method specified by the standard.

[0220] In some embodiments, the signal attenuation parameter includes a fixed attenuation amount.

[0221] For example, when using a fixed attenuation, a target attenuation for signal attenuation may be further indicated. For example, the fixed attenuation may be infinite, 0, or any other value. Alternatively, the target attenuation for signal attenuation may not be indicated. In this case, signal attenuation is performed based on a default attenuation, which may be predefined or user-set.

[0222] In some embodiments, when a preset signal attenuation method is adopted for attenuation, the signal attenuation parameter includes a parameter used to calculate the attenuation amount of the tactile signal based on a target preset signal attenuation method.

[0223] For example, when attenuation is performed based on a preset signal attenuation method, the signal attenuation parameter may be carried in a first object, such as a tactile source object or an action node object.

[0224] Optionally, when there are multiple preset signal attenuation modes, the signal attenuation mode indication is used to indicate the target signal attenuation mode among the multiple preset signal attenuation modes and the signal attenuation parameters involved in the target signal attenuation mode.

[0226] In some embodiments, the enable or disable indication is used to indicate whether to enable the pressure-related signal attenuation information (or, whether to enable the signal attenuation parameter and / or signal attenuation mode indication) when generating the tactile signal, or to determine whether to consider the signal attenuation caused by pressure when generating the tactile signal.

[0227] In some embodiments, when the enable or disable indication is used to indicate enabling of pressure-related signal attenuation information, the pressure-related signal attenuation information is considered when generating a tactile signal. When the body part-related signal attenuation information is disabled, the pressure-related signal attenuation information is not considered when generating a tactile signal.

[0228] In some embodiments, the tactile signal type indication is used to indicate the type of the tactile signal to which the pressure-related signal attenuation information applies.

[0229] It should be understood that in the above embodiments 1-5, the signal attenuation type indications may be the same or different.

[0230] In some embodiments, the signal attenuation parameter is associated with at least one of the following: the type of the haptic signal; or the frequency of the haptic signal. For example, the signal attenuation parameter is valid only for a specific type of haptic signal. For another example, the signal attenuation parameter is valid only for haptic signals within a certain frequency range, or different signal attenuation parameters are associated with haptic signals within different frequency ranges.

[0231] For example, the association between the haptic signal type and the signal attenuation parameter can also be carried in the first object, such as in the haptic source object or the action node object, for example, in the form of a <haptic signal type, signal attenuation parameter> tuple.

[0232] For another example, the association between the frequency of the haptic signal and the signal attenuation parameter can also be carried in the first object, such as in the haptic source object or action node object, for example, in the form of a <haptic signal frequency, signal attenuation parameter> tuple.

[0233] In summary, in the embodiment of the present application, when generating a tactile signal, signal attenuation information related to at least one factor among distance, time, obstructions, body parts and pressure is taken into account.
